// .NAME vtkCylindricalTransform - cylindrical to rectangular coords and back
|
|
// .SECTION Description
|
|
// vtkCylindricalTransform will convert (r,theta,z) coordinates to
|
|
// (x,y,z) coordinates and back again. The angles are given in radians.
|
|
// By default, it converts cylindrical coordinates to rectangular, but
|
|
// GetInverse() returns a transform that will do the opposite. The
|
|
// equation that is used is x = r*cos(theta), y = r*sin(theta), z = z.
|
|
// .SECTION Caveats
|
|
// This transform is not well behaved along the line x=y=0 (i.e. along
|
|
// the z-axis)
|
|
// .SECTION see also
|
|
